Industrial Applications: Problem, Solution & Benefits

Chemical Pump	Conveyor Rollers	Disposable Pump
HVAC Gears	Micro Pump	Positive Displacement Pump
Power Tools	Water Meter	Wear Rings

Application: Chemical Pump

Problem: Water-powered pump is used to dispense fertilizers, disinfectants, chlorine, acids, soaps, pharmaceuticals & nutritional supplements in a wide range of settings. Internal components are exposed to a number of chemicals, and must resist corrosion & wear against stainless steel components within the pump.

Solution:
RTP 100 Series polypropylene with PFPE.

Benefits:

Excellent wear resistance
Eliminates need for separate metal or plastic bearings
Improved coefficient of friction in moving components
Excellent chemical and corrosion resistance

Application: Conveyor Rollers

Problem: Food conveyor rollers used in food processing equipment need to withstand constant movement & must be easy to clean to reduce risk of contamination. Material used in the rollers needs to be approved for food contact & have excellent wear resistance.

Solution:
RTP 800 Series acetal with PTFE & silicone

Benefits:
• Improved wear resistance
• Excellent lubricity
• FDA compliant
• Chemical resistance to cleaning solutions

Application: Disposable Pump

Problem: Traditional metal pumps used in the food, dairy, chemical, medical and pharmaceutical industries face contamination issues, which create down-time for maintenance and high cleaning costs. Multiple material requirements include: wear resistance, maintaining low warpage and low creep at operating temperatures of 110°C (230°F), and low moisture absorption to minimize swelling.

Solution:

RTP 1300 Series polyphenylene sulfide glass fiber reinforced compound with PTFE

Benefits:

Excellent chemical resistance
No need for external lubricants
FDA compliant polymers and ingredients

Application: HVAC Gears

Problem: Due to extreme temperature changes (-40 ⁰c to 80 ⁰c) gears were creating excessive noise leading to warranty issues.

Solution: RTP 200 series and 800 series with glass fiber and PTFE.

Benefits:

Noise reduction
Low friction
Improved wear resistance

Application: Micro Pump Gears

Problem: Chemically resistant materials need to pump a wide variety of fluids over a wide temperature range including: espresso, water, pesticides, carbonated drinks, & alcohol. Application requires high wear materials but cannot utilize glass fiber.

Solution:

RTP 2200 Series Peek with carbon fiber, aramid fiber & PTFE

Benefits:
• Excellent chemical & corrosion resistance
• High strength
• Wear resistant
• High heat resistance – Many micro pumps operate at very high speeds creating high temperatures at the wear interface

Application: Positive Displacement Transfer Pump

Problem: Pump must be light weight and capable of moving hydrocarbons & other chemicals in mining, agriculture, marine, chemical, petroleum, & transportation industries in a range of environmental conditions

Solution:

Impeller: RTP 1300 Series compound with carbon fiber, PTFE & PFPE

Impeller Housing: RTP 2200 Series compound with carbon fiber, PTFE & PFPE

Wiper Blade: RTP 2200 Series compound with PTFE

Benefits:

• High strength
• Excellent chemical resistance
• Superior abrasion & wear resistance

Application: Helical Gears for Power Tools

Problem: Power tools need a lightweight moldable plastic that meets high strength and wear resistance requirements. Eliminate the need for expensive machined steel gears.

Solution:

RTP 4000 Series PPA with carbon fiber and silicone

Benefits:

• Very high strength
• Moldable to net shape
• Wear resistance
• Quiet operation
• Suitable for high speeds

Application: Water Meter

Problem: Water meter design incorporates a nutating disc, which must poses good wear properties and tight tolerances with long term water exposure.

Solution:

RTP 400 and 500 series with graphite, PTFE, silicone and or glass

Benefits:

• Tight molding tolerances
• Dimensional stability
• Hydrolytic stability
• Excellent wear properties and low coefficient of friction
• NSF approval for water contact

Application: Wear Rings

Problem: Wear rings are used in hydraulic cylinders and pistons. They require a material with good wear resistance and low coefficient of friction, and must maintain tight tolerances and perform against petroleum oils, fluids and greases over a temperature range of -40°F to +275°F.

Solution:

RTP 207A Series TFE13 Si2 HS black heat stabilized glass reinforced nylon 6 with PTFE and silicone

Benefits:

• Resistant to petroleum oils, fluids and greases
• Dimensionally stable
• Combination of good wear resistance and low
coefficient of friction
• Performs over a broad temperature range
